Is fossil evidence a challenge to faith?

Just as heliocentrism or Darwinism demanded that many religions had to readjust to a new state of things, also the fossil and geological evidence that contradicts the claims of some holy books are indigestible for those who believe at face value and without the ability to self-correct everything what is poured there. For that reason, … Read more

Our common ancestor fell from a tree and died

Australopithecus afarensis , a species to which Lucy belongs, discovered by the team of Donald Johanson, Yves Coppens and Tim White in 1974 at the Hadar site, and which existed between 2.9 and 3.9 million years ago, is considered our common ancestor. According to a study by the University of Texas at Austin, and published … Read more

Where is the largest collection of dinosaur eggs in the world?

Dinosaurs are already extinct 65 million years ago, but they inhabited it for a long time: 165 million years (humans have only been around 2 million years). Despite the fact that most dinosaur species are vegetarian, we have often imagined them bloodthirsty: not for nothing, the British scientist Richard Owen coined the word dinosaur in … Read more

The 1.2 million-year-old diet is discovered

In the Atapuerca site , evidence has been found that 1.2 million years ago of what our ancestors ate, the oldest evidence so far (and also the first test of oral hygiene). The finding has been made after the analysis of a dental calculus of the oldest hominid in Europe . The study has been … Read more

Proteins have been recovered from an 80-million-year-old dinosaur

Researchers at North Carolina State University have succeeded in recovering collagen peptides , relatively small molecules that comprise between two and a maximum of 100 amino acids, from an 80-million-year-old Brachylophosaurus , which will expand our ability to study the fossil record at the level molecular. This also confirms earlier original dinosaur collagen findings first … Read more

This is what was in a dinosaur from 180 million years ago

"In the fossil record there is very little evidence of food inside the carcasses of herbivorous dinosaurs and, until now, it had only been described in hadrosaurs and ankylosaurs," explained José Ignacio Canudo , principal coordinator of the Aragosaurus group at the University from Zaragoza that has published a study on what has been found … Read more

Violence in prehistoric times was worse than in World War II

Using an archaeological database of human burials of the remains of thousands of Central Californians dating back more than 1,000 years, it is suggested that violent death rates in populated prehistoric California exceed those of World War II. This, according to the principal investigator of this study , Mark W. Allen , an anthropologist at … Read more

The oldest fossils in the world are discovered

3,770 million years is at least the age of the remains of microorganisms that have been found in Canada, and that have become the oldest fossils that we have evidence. Specifically. small filaments and tubes formed by bacteria that lived in iron encased in layers of quartz in the Nuvvuagittuq Supracrustal Belt (NSB), in Quebec, … Read more

Fossils of a fish that lived 400 million years ago found

Brian Choo’s team from Australia’s Flinders University, together with members of the China Institute of Vertebrate Paleontology and Paleoanthropology , have found fossil remains of a fish that lived 400 million years ago. The results of the finding have been published in the journal PLoS ONE . Sparalepis tingi Baptized as Sparalepis tingi , this … Read more

This Asturian Neanderthal took ‘aspirin’

The Sidrón cave, located in Piloña (Asturias), has provided the best collection of Neanderthals in the Iberian Peninsula. Discovered in 1994, around 2,500 skeletal remains have been recovered from at least 13 individuals of both sexes and different ages who lived there approximately 49,000 years ago. An investigation by an international team of scientists, led … Read more

Were there already dental fillings 13,000 years ago?

The use of a sharp object to remove diseased cavity tissue and tar fillings appears to already exist in the Ice Age, 13,000 years ago, according to findings from a group of researchers, whose conclusions have been published in the American Journal of Physical Anthropology . Two incisors These teeth, two upper incisors, were found … Read more

Ancient human DNA detected in cave without human bones

According to an international team of scientists with the participation of the CSI, DNA from ancient human beings has been detected in cave sediments without skeletal remains, including that of El Sidrón, in Asturias. The detection technique used even identified ancient human DNA sequences from places where the Neanderthal presence has been proposed but never … Read more

This new dinosaur made nests bigger than a truck tire

A new species of giant bird-like dinosaur, called Beibeilong sinensis , has been described by a joint Sino-Canadian-Slovak team of researchers in Henan, China. The dinosaur made nests as big or larger than a truck tire (2-3 meters in diameter and probably contained two dozen or more eggs). Beibeilong sinensis This new species lived about … Read more

High-quality 3D models of 230 million-year-old fossil feces

Coprolites, the fossilized feces of animals from the past, such as dinosaurs, contain information about the animal’s lifestyle and diet that cannot be obtained from studying its skeleton. To improve their study, paleontologists from the University of Uppsala and ESRF Grenoble, thanks to the synchrotron, a type of particle accelerator in this laboratory, have conceived … Read more
